What owners say about the power train
Verbatim from NHTSA complaints, newest first
“On [XXX] while traveling to NJ, the vehicle displayed "check electrical system" and would not accept a charge. With only 40 miles of range remaining, I drove the vehicle to Jack Daniels KIA. It is STILL at the dealership, and neither the dealer nor KIA Corp has provided a date that the car will be repaired. The dealer told me that it is covered under the 100kmi powertrain warranty, but that KIA corp must direct how and what to fix. They continue to supposedly try different things to fix the car, but either are not applying resources or are ignorant in how to fix the vehicle. KIA will also not compensate me $1308.99 to cover my current losses (car note, uber to get home when it died, and fuel costs) to date. The car has been out of my possession now for 44 consecutive days straight without any end in sight, compensation, or expected repair date.”
“Vehicle would not start/drive. Vehicle was parked in garage at time of failure. Kia dealership said the ICCU needed to be replaced along with the 12V battery. Prior to the failure, audio was not working in the car for several weeks. Kia stated that was due to the ICCU issues and that the 12V was most likely also failing due to the ICCU. ICCU was covered by KIA, but owner of the vehicle had to pay for the replacement of the 12V battery. Vehicle was inspected by manufacturer at the local Kia dealership.”
“This make/model has a known ICCU issue. Ours went out just after warranty expired and the cost is 4,000. The EU and some Asian countries have extended the warranty of this fault due to how prevalent it is.”
“I was unable to charge this electric vehicle which I normally do almost once or twice a week using my home level 2 charger. It also did not speak the message that "your vehicle is being charged" which it normally does when I charge the vehicle. I tried multiple times. Then I got into the vehicle and saw that it was giving me the following error messages (pics included below) upon trying to start it. 1. "Check Electric Vehicle System" 2. "Battery Discharge Warning - Please use the vehicle after starting the vehicle". However the vehicle would not start and then it went went totally dead. Kia was kind enough to tow it under warranty to Century Kia in Tampa, FL as well as now they are trying to identify the issue. Kia was also kind enough to provide me a rental via Century Kia which I appreciate.”
“The iccu failed on this car rendering the whole vehicle useless. This part is currently a recall and I was using a new ICCU with the software update per their recall solution. My second ICCU failed at approximately 40k miles.”
“While driving the vehicle a short distance, I heard a loud pop from the back seat. The car immediately warned of an electrical system failure. The issue and symptoms are consistent with ICCU module failures, reported across the kia/hyundai egmp platform. My safety was put risk, because I was stopped in heavy traffic when this happened and could have been stranded far from home with no ability to drive the vehicle more than a couple of miles at most. The warnings started immediately after the pop I heard.”
